One of the reason why ophthalmology ( study about eye) is interesting mainly because we could see lots of beautiful pictures, mentioning that I am a huge fan of watching movies, so visual is a treat for me. So, I want to dedicate this series to help learning more about the amazing part of eye. This chapter will discuss about the angle of the eye, where if any abnormalities found will result in a disease called Glaucoma. We used an equipment named Gonioscopy to assess the depth of the angle of the eye.
